This is actually based on the book "The Experiment" by John Darnton

Rating: 6/10 (27 April 2020)

I read The Experiment years ago and it was an ok book. When this movie came out I just assumed it was based on the book. In fact, the author of The Experiment, John Darnton, is not credited at all. I don't understand the details behind how they got around that, but without a doubt the writers based it on his book.
The entire premise is exactly the same. The whole idea of clones being raised ignorant of their purpose. In The Experiment, they were on a small island off the coast of Georgia. In the movie, they are told they will go to The Island. Two clones fall in love. Escaping to find the ones they are cloned from. It's all the same, except the movie has been "hollywood jazzed up" with car chases, shootouts, etc.
